This project demonstrates an Arduino-based LCD button counter using the Arduino UNO R4 WiFi and an I²C LCD display. The sketch counts button presses, debounces the input, toggles an LED, and displays ...

In this tutorial we are going to interface a seven segment display to ARDUINO UNO. The display counts from 0-9 and resets itself to zero. Before going further, let us first discuss about seven segment ...

LCDs are widely used in applications like token-display machines in s malls and supermarkets, order number displays in restaurants and café, and so on. The project presented here demonstrates the ...

In this project, we made a social distancing system using Arduino and sensors. This Social Distancing System would ensure that people follow social distancing on the streets as well as in the shops.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

The frequency counter project operates with 40MHz while integrating an 8-digit LCD display. The device can be an optional offsets for use in a receiver or transceiver while having 10Hz resolution.

As promised in the first part of this article, now it is time to see in detail how we can use the Alphanumeric LCD Display in our Arduino sketches. The idea beside this project is to give a simple ...
